greivous was a dip stick anyway... he was a really really dumb general, cowardly and such, he lost alot of battles because he was afraid of the big bad jedi man.
plus i dont think he was getting enough oxygen to his brain due to the awesome force crush delivered by the one and only Masta Windu. He probably made a lot of bad decisions due to his brain cells dieing.
he wasn't afraid; Dooku taught him to run away from fights he couldn't win, so he could continue to command the droid army. another thing- Grievous didn't really need a lot of oxygen in the first place. the Geonosians designed him so he barely needed any oxygen to control his body.
If you read "Labyrinth of Evil" by James Luceno, then you would know that the
Invisible Hand (the ship in question) had been in many battles before the attack on Coruscant, so it was probably in need of repair and/or have many weak points
